FreeRunner SIM compatibility

So far there were no credible reports of any issues left with any sim cards after upgrading GSM firmware. So, basically, if it works with any old GSM phone, it will work with GTA01 and GTA02 too after firmware upgrade.

SIM is from the days of Cingular, so it's very old. Om2007.2 showed "Registering...". Om2008.12 did not acknowledge the SIM. QT-Extended said "Sim not detected". Used friend's SIM and was able to place a call immediately. Current is 4020, tested with 4022.
